Abstract
An emergence cuff (30) formed of suitable biocompatible synthetic plastic is shown having a bore adapted to be received on an abutment in turn mounted on a root member implanted in the alveolar ridge of a patient. The cuff has a bore (36) generally matching the crown receiving surface of the abutment and an outer surface which goes from a feathered edge portion with the bore at the end (34) closest to the root member and a larger outer surface at the second end. The gum tissue is sutured onto the cuff and abutment so that after sufficient healing when the cuff is removed a sulcus is formed to receive a crown with the interface of the crown and the abutment located below the gum line. The emergence cuff can also serve as the cervical portion of a temporary crown (40) by cementing or bonding it thereto, if desired.
